Keyed Locks

I used to lock up my street clothes and carry a key around while I was at the gym. I lived in constant fear that I would lose the key, so I developed the habit of tapping my pocket whenever I stood up to make sure it hadn't fallen out. Losing it while wearing my gym clothes around wouldn't have been that big of a deal. I suspect that I could have gone to the desk and convinced them to bring a bolt cutter into the locker room to get me my stuff back. It was more a concern in the locker room. If I dropped that key down the shower drain, I'd be the guy wearing a towel asking other guys in the locker room to go to the front desk to try and convince someone to come to the locker room with a bolt cutter to open someone else's locker. It would be tough to ask so much of a stranger.
